'''Nuclear pseudoinclusions''' | '''Nuclear pseudoinclusions''' are cytoplasmic invaginations into the nucleus that mimic true nuclear inclusion. | ||
Tumours | ==Nuclear pseudoinclusions and true nuclear inclusions== | ||
True nuclear inclusions consist of material that is: | |||
# Foreign to the nucleus. | |||
# Completely contained within the nucleus. | |||
They are classically caused by viral particles; however, there are other causes.<ref name=pmid21081532>{{Cite journal | last1 = Ip | first1 = YT. | last2 = Dias Filho | first2 = MA. | last3 = Chan | first3 = JK. | title = Nuclear inclusions and pseudoinclusions: friends or foes of the surgical pathologist? | journal = Int J Surg Pathol | volume = 18 | issue = 6 | pages = 465-81 | month = Dec | year = 2010 | doi = 10.1177/1066896910385342 | PMID = 21081532 }}</ref> | |||
